THIS SERVICE BULLETIN EXPLAINS THIS NORMAL PHYSICAL PHENOMENON. EACH LAMP HOUSING CONTAINS A QUANTITY OF \"TRAPPED\" AIR. THIS AIR CONTAINS WATER THAT IN HUMID OPERATING CONDITIONS OR SUDDEN VARIATIONS IN TEMPERATURE (E.G.: AFTER CLEANING IN THE WASHING BAY) CAN CONDENSE IN THE LAMP HOUSING. THE CONDENSATE PRESENTS ITSELF IN THE FORM OF MIST OR SMALL DROPS OF WATER THAT SETTLE ON THE COLDEST PART OF THE HOUSING. MOST OF THE TIME, THE PHENOMENON OCCURS WHEN DRIVEN THROUGH RAIN FOR A LONG TIME OR STORED FOR A LONG TIME AT LOW TEMPERATURE. NORMALLY, THE CONDENSATE DISAPPEARS AFTER SOME TIME WHEN THE VEHICLE IS USED IN DRY SURROUNDINGS.","document":null,"url":"https://open.wenmarpro.com/bulletins/10084371","components":[{"id":"lighting","name":"Lighting","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"VAN HOOL","model":"VAN HOOL","year_from":null,"year_to":null,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
